Forty is a significant number in history. It is a number representing transition, testing and change. I have just spent forty days away from the office going through such a transition. It was an important time with my family, and it also offered me a rare space for reflection. During this time I have come to the extremely difficult conclusion that it is time for me to leave RTG and AMD.

I have no question in my mind that RTG, and AMD, are marching firmly in the right direction as high-performance computing becomes ever-more-important in every aspect of our lives. I believe wholeheartedly in what we are doing with Vega, Navi and beyond, and I am incredibly proud of how far we have come and where we are going. The whole industry has stood up and taken notice of what we are doing. As I think about how computing will evolve, I feel more and more that I want to pursue my passion beyond hardware and explore driving broader solutions.

I want to thank Lisa and the AET for enabling me to pursue my passion during the last four years at AMD, and especially the last two years with RTG. Lisa has my utmost respect for exhibiting the courage to enable me with RTG, for believing in me and for going out of her way to support me. I would also like to call out Mark Papermaster who brought me into AMD, for his huge passion for technology and for his relentless support through many difficult phases. And of course, I want to thank each and every one of my direct staff and my indirect staff who have worked so hard with me to build what we have now got. I am very proud of the strong leaders we have and I'm fully confident that they can execute on the compelling roadmap ahead.

I will continue to be an ardent fan and user of AMD technologies for both personal and professional use.

As I mentioned, leaving AMD and RTG has been an extremely difficult decision for me. But I felt it is the right one for me personally at this point. Time will tell. I will be following with great interest the progress you will make over the next several years.

On a final note, I have asked a lot of you in the last two years. You've always delivered. You've made me successful both personally and professionally, for which I thank you all from the bottom of my heart. I have these final requests from you as I leave:

Polaris was good until Ethereum boom. Still, riding too long on GCN with mere 4 shader engine and same front and back end thats been stuck since Hawaii. I dont care what they say, there is no replacement for displacement. Period. They either need more or design new arch to be competitive.

Better than Crossfire/SLI does. These guys aren't dropping support for parts of those things for no reason... It's because it needs to be seamless to the end user, not all out in the open like multi-GPU is today. DX12 is also all about that. The groundwork for making these moves is already laid, but it'll take some time before they roll it all into useful tech.

It's only blind fanboys that think that DX12 Multi-GPU will mean you can use AMD and NV together... it's about something so much different, really, but some lack the broad thinking to see what's coming IMHO.

But how many games support D3D12 multi-GPU? Do the developers have to do anything special to make it work? If it isn't something native to the API, Navi and similar multi-GPU architectures are going to perform horribly. On top of that, all these little chips need to be connected to the same memory controller or else it will have to get into the business of duplicating memory (nothing but bad news there).
